Poisoning by ganglionic blocking drugs, accidental, init

This code signifies an accidental overdose or adverse reaction to a ganglionic blocking drug, resulting in toxic effects. These medications primarily interfere with nerve impulse transmission in the autonomic nervous system, and poisoning can lead to significant cardiovascular and gastrointestinal symptoms.

Apply this code when a patient presents for initial treatment of an unintentional poisoning by a ganglionic blocking agent. This includes scenarios such as accidental ingestion of an incorrect dose, medication mix-up, or an unforeseen adverse reaction to a prescribed ganglionic blocker.

• Always confirm the intent of the poisoning (accidental, intentional self-harm, assault, undetermined) as this impacts the 5th character.
• Ensure the encounter is the "initial encounter" for the poisoning event. Subsequent care for the same poisoning would use a different 7th character.
• Code any associated signs and symptoms or specific organ damage resulting from the poisoning in addition to this code.
